概述： 获得性免疫缺陷综合征（艾滋病）是20世纪70年代末在美国发现的。。。 Hints: Acquired Immune Deficiency Syndrome AIDS HIV Latinos PS:14秒左右有破折号
Acquired Immune Deficiency Syndrome (AIDS) was diagnosed in the United States in the late 1970s. Since then, AIDS has killed more than 204,000 Americans - half of that number in the past few years alone. Another 185,000 of the 1 million infected with the HIV virus are expected to die within the next year. Nearly half of those diagnosed with the virus are blacks and Latinos. Women and youth in rural southern communities now constitute the fastest growing segment of people with AIDS. Despite such alarming numbers, the federal and state governments have been slow in implementing programs to stop the spread of AIDS.
获得性免疫缺陷综合征（艾滋病）是20世纪70年代末在美国发现的。自那时以来，艾滋病已夺走了20.4万多美国人的生命——其中有一半是在过去几年中丧生的。此外，在100万感染艾滋病病毒的人当中有18.5万人也将在一年内死亡。 被诊断感染艾滋病病毒的人当中有一半是黑人和来自拉丁美洲的美国人。南部农村社区的妇女和青年是数量增长最快的艾滋病患者群体。 尽管数量大得惊人，但联邦和各州政府在实施防止艾滋病蔓延的计划方面行动迟缓。
